Why, it may be said, who is there that is not against us? Why the world is against us, both kings and peoples, both relations and countrymen. Yet these that be against us, so far are they from thwarting us at all, that even without their will they become to us the causes of crowns, and procurers of countless blessings, in that God's wisdom turns their plots unto our salvation and glory. See how really no one is against us! For it was this which gave new lustre to Job, the fact that the devil was in arms against him. For the devil moved at once friends against him, his wife against him, and wounds, and servants, and a thousand other machinations. And it turned out that none of them was against him on the whole. And yet this was no great thing to him, though it was great in itself, but what is a far greater thing is, that it turned out that they were all for him. For since God was for him, even things seemingly against him all became for him. And this happened with the Apostles also, inasmuch as both the Jews, and they of the Gentiles, and false brethren, and rulers, and peoples, and famines, and poverty, and ten thousand things were against them; and yet nothing was against them. For the things which made them the most bright and conspicuous, and great in the sight both of God and of men, were these. Just reflect then what a word Paul has uttered about the faithful, and those who are truly (ἀ κριβὥς) crucified, such as not even the Emperor with his diadem can achieve. For against him there are abundance of barbarians that arm themselves, and of enemies that invade, and of bodyguards that plot, and of subjects many that oftentimes are ever and anon rebelling, and thousands of other things. But against the faithful who takes good heed unto God's laws, neither man, nor devil, nor anything besides, can stand! For if you take away his money, you have become the procurer of a reward to him. If you speak ill of him, by the evil report he gains fresh lustre in God's sight. If you cast him into starvation, the more will his glory and his reward be. If (what seems the most severe stroke of all) you give him over to death, you are twining a crown of martyrdom about him. What then is equivalent to this way of life, being that against which nothing can be done, but even they that seem to devise mischief are no less of service to him than benefactors? This is why he says, “If God be for us, who can be against us?” Next, not being satisfied with what he had already said, the greatest sign of His love for us, and that which he always is dwelling over, that he sets down here also; I mean, the slaying of His Son. For He did not only justify us, he means, and glorify us, and make us conformed to that Image, but not even His Son did He spare for you. And therefore he proceeds to say,
Ver. 32. “He that spared not His own Son, but delivered Him up for us all, how shall He not with Him also freely give us all things?”
And here the words he uses are high-wrought (μεθ᾿ ὑτερβολἥς) and exceedingly warm, to show his love. How then is He to neglect us, in whose behalf “He spared not His own Son, but delivered Him up for us all?” For reflect what goodness it is not to spare even His own Son, but to give Him up, and to give Him up for all, and those worthless, and unfeeling, and enemies, and blasphemers. How then shall He not with Him also freely give us all things? What he means then is much as follows; If He gave His own Son, and not merely gave Him, but gave Him to death, why doubt any more about the rest, since you have the Master? Why be dubious about the chattels, when you have the Lord? For He that gave the greater thing to His enemies, how shall He do else than give the lesser things to His friends?
Ver. 33. “Who shall lay anything to the charge of God's elect?”
Here he is against those who say, that faith is no profit, and will not believe the complete change. (i.e. in baptism see p. 349.) And see how swiftly he stops their mouths, by the worthiness of Him that elected. He does not say, “Who shall lay anything to the charge of God's” servants? Or of God's faithful ones? But “of God's elect?” And election is a sign of virtue. For if when a horse-breaker has selected colts fit for the race, no one can find fault with them, but he would get laughed at who should find fault; much more when God selects souls are they that “lay any charge against” them deserving of laughter.
“It is God that justifies.”
Ver. 34. Who is He that condemns?
He does not say, it is God that forgave our sins, but what is much greater, “It is God that justifies.” For when the Judge's sentence declares us just, and a Judge such as that too, what signifies the accuser? Hence neither is it right to fear temptations, for God is for us, and has shown it by what He has done; nor again Jewish triflings, for He has both elected and justified us, and the wondrous thing is that it was also by the death of His Son that He did so. Who then is to condemn us, since God crowns us, and Christ was put to death for us, and not only was put to death, but also after this intercedes for us?
For, “It is Christ,” he says, “that died, yea rather, that is risen from the dead, Who is at the right hand of God, Who also makes intercession for us.”
